Along with the continuous development of the printing industry in the application of environmental protection technology, the ink will become represent the general trend. Here we have to introduce the characteristics of environmental protection with soy ink. 

Environmental protection soybean oil ink is non-toxic, tasteless, no organic solvent volatile matter, low cost, wide material source, good gloss, high analysis of resistance, heat resistance, abrasion resistance and are resistant to washing and economic health characteristics. Environmental protection soy ink according to the usage of the product, can be divided into: high gloss, gloss, Matt ordinary three. From the screen process can be divided into: manual screen printing and screen two types of rotary screen printing. The water temperature in the process of using screen printing ink, can eliminate the harm to human body and pollution to the environment, has been paid attention to by food, artificial leather, bags and other packaging and printing enterprises. 

In addition to environmental protection, environmental protection soybean ink and solvent based screen printing ink also has the following advantages: 

1 strong wear resistance. Packaging and printing jewelry needs a strong wear resistance to 50 per square centimeter of pressure measurement, the general should achieve 150 wipe per cent, the brightness of the general, can reach 50 ~ 70 brightness units. Therefore, the packaging of silk screen products not only to wear, 30 `8d_ clock, and the water wash, but at a high of 121 degrees to 150 degrees Celsius (3 seconds to 10 seconds) to meet the requirements. 

After the 2 film speed, quick drying. Environmental protection soybean ink drying process 60% is through evaporation or evaporation, 40% by material penetration and absorption, dry quickly, about a few minutes or tens of minutes to complete the printing ink. If the use of infrared or hot air drying method can promote the film drying. 

3, safe and convenient use and storage, is conducive to safe production and operation to improve the working conditions of the employees. As a solvent or oil printing ink is dangerous goods category, transport, storage, use very inconvenient. The environmental protection type high temperature resistant waterborne printing ink with water as solvent, without any risk, the use of safe and reliable water cleaning equipment and cleaning finger. 

After understanding the characteristics and advantages of environmental protection soybean oil, will be for the future of environmental protection printing work to help.
